(Note-1): Set the input signal detection direction of Q170MCPU's internal I/F (DI) in the "Q170M I/O Setting" of System Settings.
(Note-2): The mark detection signal compensation time cannot be set if "Invalid" is selected in the estimate calculation. (0[µs] is set.)
(Note-3): This setting can be ignored.
